We consider a hybrid setup in which the antineutrino run of
T2HK is replaced with antineutrinos from muon decay at rest ($\mu$-DAR). Such a setup benefits
from having higher statistics in both neutrino and antineutrino modes, and suffers
from lower beam-on backgrounds. In addition, systematic effects are reduced.
We find that this hybrid setup in conjunction with data from T2K and NO$\nu$A
has a good potential for determining the unknowns in neutrino oscillation
physics, namely the mass hierarchy, octant of $\theta_{23}$ and $\delta_{CP}$.
